When opening the mold, the gas pressure rod on the injection molding machine can be used to cooperate with the mold opening base 3 to automatically open the upper mold 1 and the lower mold 2, making it more convenient to open the mold and speeding up the production efficiency.

[0025] Specifically, the upper mold 1 includes an upper mold pressing plate 11 , and an upper mold plate 12 is fixedly connected to the bottom surface of the upper mold pressing plate 11 .

[0026] The upper mold plate 11 is used for installation with the injection molding machine.

[0027] Specifically, the upper mold pressing plate 11 includes an upper mold pressing plate body 111 , and an injection port 112 is fixedly connected to the middle of the upper mold pressing plate body 111 .

[0028] Specifically, the upper template 12 includes an upper template body 121, the bottom surface of which is provided with an upper model cavity 122, and two groups of upper mold cooling channels 123 are provided in the upper template body 121. The outer ends of the water outlet and water inlet of the upper mold cooling channel 123 are fixedly connected with a water pipe connecting nozzle 4.

[0029] The upper mold cooling channel 123 is used to connect to an external water source to facilitate rapid cooling of the injection molded spray gun housing.

[0030] Specifically, the upper mold cavity 122 is composed of two upper mold cavities, and the two upper mold cavities are respectively matched with two buckling shells of the spray gun housing.

[0031] The two upper cavities 122 are used for injection molding two spray gun housings that are buckled together.

[0032] Specifically, the lower mold 2 includes a lower mold body 21, a lower model cavity 22 is opened at the upper end of the lower mold body 21, the lower model cavity 22 is opposite to the upper model cavity 122, and two groups of lower mold cooling channels 23 are opened in the lower mold body 21. The outer ends of the water inlet and outlet of the lower mold cooling channel 23 are fixedly connected with a water pipe connecting nozzle 4.

[0033] Specifically, the lower mold cavity 22 is composed of two lower side mold cavities, and the two lower side mold cavities are respectively matched with two snap-fit ​​shells of the spray gun housing.

[0034] Specifically, the mold opening base 3 includes a base plate 31, and the two sides of the upper end of the base plate 31 are fixedly connected with side support plates 32 in the horizontal direction. The upper ends of the side support plates 32 are fixedly connected to the lower template body 21, and a top plate 33 is sleeved between the two side support plates 32. A plurality of ejector rods 34 are fixedly connected to the top plate 33. The upper ends of the ejector rods 34 pass through the lower template body 21 and contact the bottom surface of the upper template body 121, and the ejector rods 34 are located on the periphery of the lower model cavity 22 and the upper model cavity 122.
